It's actually just a list of your favorite releases of this year, like one year ago!
Since MM'15 was a bit boring and Kobushi weren't as active as I would have liked, ANGERME was the only thing that kept me interested in H!P. So, I had the need to crawl back to my K-pop habitat that I left to introduce myself to J-pop. Because of that, this year's list is twice as big as the one I made for 2014, good job 2015.

Top 3:

1. IU - Zezé ····· Thanks to the controversy over this song, I gave it a listen and I loved it so much. To this day I still don't know if it was a stupid witch-hunt or she intended to be incorret, either way I can't put #1 any other song than Zezé.

2. T-ara - So Crazy ····· I'm not even a T-ara fan but I'm always super biased with their songs.

3. SNSD - You think ····· I don't understand why Lion Heart got all the attention honestly. Or why all of their You think performances are pre-recorded.

Favorites:
KARA - Cupid ····· This one flopped so hard but I was obsessed with this song when it came out. If they finally don't renew their contracts this month it will be sad how Cupid was their last song.
SNSD - Check & Sign ····· Sign is the only song I liked from Lion Heart and Check one of the few things that save SNSD this year for me.

Seventeen - Mansae ····· I hope this guys can make it big and I hope Pledis does not fuck them up.

F(x) - 4 Walls ····· I now F(x) always has the highest quality album songs, maybe I should give it a listen.

Love:
SNSD - Catch me if you can & Party ····· I know at first I didn't like Party but as catchy as it is, it grew on me a lot. Those 'it's a party' lines are still stupid and pointless tho.
Miss A - Only you ····· Just like Party, I didn't really like this at first but with a couple of listens I started liking this. It's still less than what Miss A can offer but...
Gfriend - Me gustas tú & Glass Bead ····· Their songs aren't even my type but what makes me like them so much is their choreographies
Twice - Like OOH-AHH
Girl's Day - Ring my bell
Taeyeon - I
Brown Eyed Girls - Warm Hole

OK:
Rainbow - Black Swan ····· I like Rainbow and I've said multiple times that I want them to go back to their A style. This is a nice change, it's not sweet or sugary at all but it's not what I was waiting for. I hope they can release A 2.0 before disbanding.

4Minute - Crazy ····· Maybe it's because it was an early release that it has ended down here.
Dal Shabet - Joker ····· Just forget that atrocious rap please, just please.
Seventeen - Adore U

21:04 - Ap2000: It is time for you to write "s the only K-pop song I remember from 2015, but I like it so much that it could make up for a whole year devoid of other music."22:15 - aine: I'm afraid22:15 - aine: that post would be empty22:15 - aine: because I heard like 0 kpop in 2015

To clarify, I meant 0 songs released in 2015 that I would remember. Sorry, Korea, no cookie this time (but I'll use Derby's links to perhaps find something memorable).

Stellar - Vibrato. You can never go wrong with that sweet, sweet Sweetune sound. It makes you wonder if this would have gone to Nine Muses if they were still working with them. (As an aside, Stellar is currently crowdfunding their next album.)

myB - My Oh My. A group with an incredibly goofy personality. They were very quick to already have a reality show on MTV (Lee Jung's my Baby), so I'm curious of their future.
